Introduction
In general, hyperthyroidism, also known as thyrotoxicosis, is an endocrine disorder characterized by excessive synthesis and release of thyroid hormones from the thyroid gland, leading to increased metabolic activity and sympathetic nervous system stimulation. Patients with hyperthyroidism should strictly follow a low-iodine diet, avoiding high-iodine foods such as kelp and seaweed, and choose iodine-free salt.
Generally, hyperthyroidism, the full name of which is hyperthyroidism, is an endocrine disorder caused by excessive synthesis and release of thyroid hormones by the thyroid gland, leading to increased metabolic rate and sympathetic nervous system activation. Detailed analysis is as follows:
Hyperthyroidism is an endocrine disease caused by excessive production of thyroid hormones by the thyroid gland. Excess thyroid hormone accelerates whole-body metabolism, causing symptoms such as heat intolerance, excessive sweating, palpitations, hand tremors, increased appetite with weight loss, emotional excitability, and insomnia. It may also be accompanied by signs like exophthalmos (bulging eyes) and goiter (enlarged thyroid gland). Long-term lack of proper treatment can damage the cardiovascular system, causing arrhythmias and heart enlargement, and can also affect bone health, potentially leading to serious complications such as osteoporosis.
Patients with hyperthyroidism should strictly follow a low-iodine diet, avoiding high-iodine foods such as kelp and seaweed, using non-iodized salt, and reducing intake of irritating foods. Lifestyle should be regular, ensuring sufficient sleep, avoiding staying up late and excessive fatigue. Patients may engage in moderate relaxing exercises such as walking or yoga, but should avoid strenuous physical activity.
